Associate Professor
My research primarily focus on efficient computations in digital circuits both ASIC and FPGA. The applications cover a wide area, although communication is frequently recurring.
To not perform computations is the most efficient way to realize them
All computations will require energy, so by performing the computations as efficient as possible or even avoid making computations can provide large energy savings. One way to avoid performing computations is to select to perform computations where the result can be reused for multiple other computations.
Besides educating I am also working as a Head of the Division of Computer Engineering, DA.
